Status changed to 'Confirmed' because the bug affects multiple users.

[Sebastien Bacher (seb128)]

upstream says it's working for them, we should try again once we have 1.2.2 ... Aron how is that update going?

[Aron Xu (happyaron)]

@seb128, this is another issue from what we've SRUed to Xenial, it's more about files with certain extensions aren't showing up in the selection list.

As a workaround, you can drag and drop your private key directly from Files (Nautilus)
